hey, when starting the game S.T.A.L.K.E.R. Shadow of Chernobyl, you get the post-game video as normal on most games. But when thats done, I get a black screen with some guy talking to my character about some stuff. I've read the walkthrough and it said I should have been asked about the tutorial. I was never asked by the game if I wanted to do it or not. It just left me with a black screen. Even then I tried to playing the game, but came across a locked door, what can I do?
